Top SchoolSerhii Kostenko is a Middle DevOps Engineer with eight years of hands-on experience building and operating cloud-native infrastructure, currently based in Lisbon. He has driven platform migrations from Mesos/Marathon to Kubernetes, automated deployments with Ansible, and managed Azure infrastructure with Terraform, combining strong Linux and containerization expertise with observability tooling like Prometheus, Grafana and Loki. Serhii has improved CI/CD and migration workflows—moving teams from semi-manual pipelines to GitLab CI—and supported transitions from monoliths to microservices in production environments. His background spans on-call incident response, root-cause analysis, and infrastructure-as-code at startups and scale-focused teams, reflecting a pragmatic balance of stability and automation.
